Abstract: Concentrated suspensions of smectite clays are obtained as either relatively "thin" or highly shear-thinning slurries that are easy to pump, by adding one or more of certain cationic polymers whose weight average molecular weight, Mw, is 50,000 or higher. It was found during the course of the invention that a cationic polymer with an Mw of 10,000 did not work, while the same polymer with a bimodal Mw of 50,000 and 30,000 worked satisfactorily. To achieve the full advantage of the present invention, the cationic polymer preferably has 1 to 10 milliequivalents of cationic charge per gram of the polymer, and more preferably 5 to 10 milliequivalents of cationic charge per gram of the polymer, and most preferably 6 to 8 milliequivalents of cationic charge per gram of the polymer.
Abstract translation: 通过加入一种或多种重均分子量Mw为50,000或更高的某些阳离子聚合物，获得蒙脱石粘土的浓缩悬浮液，作为易于泵送的相对“薄”或高剪切稀化浆料。 在本发明的过程中发现，Mw为10,000的阳离子聚合物不起作用，而具有50,000和30,000的双峰Mw的相同聚合物工作令人满意。 为了实现本发明的全部优点，阳离子聚合物优选每克聚合物具有1至10毫当量的阳离子电荷，更优选每克聚合物具有5至10毫当量的阳离子电荷，最优选6至8个 每克聚合物的阳离子电荷的毫当量。
